Three-phase imbalance is an important indicator of power quality. Although there are many factors that affect the power system, normal imbalance is mostly due to asymmetry of three-phase components, line parameters or loads. Since the three-phase load factor is not certain, the three-phase voltage a

Abnormal soundWhen the transformer is operating normally, it will emit a continuous and uniform "buzzing" sound. If the sound generated is uneven or has other special sounds, it should be considered that the transformer is not operating normally, and the fault can be found based on the dif

Transformer impulse voltageTransformer Impulse Voltage refers to the transient high voltage pulse suddenly applied to the transformer insulation system due to changes in weather conditions, lightning strikes, etc. in the power system. This pulse voltage has very high peak voltage and fast rise time

1. Abnormal forms and treatment methods of transformer cooler1. Main abnormal forms: Transformer cooling methods include oil-immersed air cooling, oil-immersed self-cooling, forced oil circulating air cooling, forced oil circulating water cooling, etc. Oil-immersed air cooling relies on hot oil self
